Union of Concerned Scientists: Back in 2012, after the Competitive Enterprise Institute and the National Review each published pieces that likened climate scientist Michael E. Mann to a child molester and called his work a fraud, Mann fought back with a lawsuit, charging them with libel. Now, in a preliminary ruling, a Superior Court Judge has sided with Mann, paving the way for the case to move forward and potentially setting an important precedent about the limits of disinformation.
The ruling, in essence, reinforces the wise adage attributed to former New York Sen. Patrick Moynihan that, while everyone is entitled to his or her own opinion, we are not each entitled to our own facts. But first, some background.
Michael Mann, a world-renowned climate scientist at Penn State University, is perhaps best known as the author of the so-called “Hockey Stick” graph. Some 15 years ago, in 1999, Mann and two colleagues published data they had compiled from tree rings, coral growth bands and ice cores, as well as more recent temperature measurements, to chart 1,000 years’ worth of climate data. The resulting graph of their findings showed relatively stable global temperatures followed by a steep warming trend beginning in the 1900s. One of Mann’s colleagues gave it the nickname because the graph looks something like a hockey stick lying on its side with the upturned blade representing the sharp, comparatively recent temperature increase. It quickly became one of the most famous, easy-to-grasp representations of the reality of global warming.
The United Nations’ Intergovernmental Panel on Climate Change featured Mann’s work, among similar studies, in their pathbreaking 2001 report, concluding that temperature increases in the 20th century were likely to have been “the largest of any century during the past 1,000 years.” But while Mann’s peer-reviewed research pointed clearly to a human role in global warming, it also made Mann a lightning rod for attacks from those, including many in the fossil fuel industry, who sought to deny the reality of global warming.
